[0014] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0015] like Figure 1 As shown, a 4G suction cup antenna for wireless meter reading of the utility model includes a steel wire 1, a metal connecting rod 2, a small suction cup 3, a card seat 5, and a coaxial cable 8;

[0016] The metal connecting rod 2 is detachably arranged on the upper end of the small suction cup 3, the steel wire 1 is fixed above the metal connecting rod 2, and the lower end of the metal connecting rod 2 is connected to the inner conductor part of the coaxial cable 8 by tin welding; the braided mesh part of the coaxial cable 8 is pressed on the edge of the small suction cup 3 through the magnet cover 4, and is conductive with the magnet cover 4, and the other end of the coaxial cable 8 is connected with a joint connector 10; the socket 5 is connected to the small suction cup 3.

[0017] In this embodiment, the magnet assembly consists of a magnet 6-1 and a metal cover 6-2, and is fixed in the small hole of the holder 5 by gluing. The metal cover 6-2 protects the magnet 6-1, and the positive and negative directions of the magnet assembly will affect the suction force of the magnet.

[0018] In this embodiment, the steel wire 1 is arranged in an elastic whip-like structure, and a plug hole is arranged at the lower end of the steel wire 1. The upper end of the metal connecting rod 2 can be detachably embedded in the plug hole of the steel wire 1, so that it is easy to install and disassemble.
